Owners of the 2020 Chevrolet Blazer AWD with the 3.6L V6 engine get 21 MPG combined. It’s a figure that won’t win any awards, falling short of hybrid territory and even some more modern turbocharged competitors, but it represents a compromise for buyers who want capability, power, and the Blazer’s distinctive style. These owners aren’t hyper-focused on maximizing every last mile per gallon. They value the sure-footedness of all-wheel drive and the reliable engine, which is why they selected this particular configuration.

City and highway performance

The EPA estimates the 2020 Chevrolet Blazer AWD 3.6L at 18 MPG in the city and 25 MPG on the highway. The city rating reflects the engine’s thirst in stop-and-go traffic, which is typical behavior for a naturally aspirated V6 in a vehicle of this size. The highway number is more respectable, helped by the Blazer’s aerodynamic design and the smooth-shifting 9-speed automatic transmission. The transmission is programmed to select higher gears early to maximize fuel efficiency at cruising speeds. However, expect the highway MPG to dip if you frequently drive at speeds significantly above posted limits, or if you’re constantly making passing maneuvers that require downshifting.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2020 Chevrolet Blazer AWD 3.6L to be exactly $2,100. This figure is based on driving 15,000 miles per year and using the EPA’s estimated combined fuel economy of 21 MPG, assuming the then-current national average fuel price. Individual fuel costs will vary depending on local fuel prices and your personal driving habits. Those with longer commutes or more aggressive driving styles will spend more than $2,100, while those who primarily drive short distances, or who prioritize fuel efficiency, may spend less.

Real-world expectations

While the EPA provides a standardized testing methodology, real-world MPG can deviate. Expect your mileage to fluctuate based on factors like driving style, traffic conditions, weather, and terrain. If you predominantly drive in the city with frequent acceleration and braking, achieving 18 MPG might be challenging. Conversely, long highway road trips at consistent speeds can potentially yield figures closer to, or even slightly exceeding, the EPA’s 25 MPG rating. Regular maintenance, including properly inflated tires and timely oil changes, also plays a crucial role in maintaining optimal fuel efficiency. Be sure to check BLAZER MPG across all years, to see how it measures up to other model years of the Blazer.

How it compares

The 2020 Chevrolet Blazer’s fuel economy sits in a competitive market. The Honda Passport, another mid-size SUV with a V6 and standard all-wheel drive, achieves an EPA-estimated combined MPG of 21, mirroring the Blazer. However, smaller turbocharged competitors like the Toyota RAV4 offer significantly better fuel economy. The RAV4 Hybrid, for example, boasts an impressive 40 MPG combined. Even within the Chevrolet lineup, you’ll find significant variation. For example, consider looking at all Chevrolet fuel economy data, and comparing that to the figures for the smaller Chevrolet Equinox with its available turbocharged engine, is far more frugal, though lacking the Blazer’s strong power and bolder styling. The Blazer’s fuel consumption is a choice for those who prioritize V6 power and all-wheel drive grip in a stylish package, but it’s important to be aware of the more efficient alternatives.

Tips to maximize efficiency

Avoid aggressive acceleration and braking. The Blazer’s 3.6L V6 responds well to a gentle touch. Gradually accelerate from a stop and anticipate traffic patterns to avoid hard braking. Using cruise control on the highway helps maintain a consistent speed, minimizing unnecessary fuel consumption.

Regularly check and maintain your tire pressure. Underinflated tires increase rolling resistance, which negatively impacts fuel economy. Consult the sticker on your driver’s side doorjamb for the recommended tire pressure and maintain it regularly.

Reduce unnecessary weight. Carrying excessive cargo in your Blazer puts additional strain on the engine, leading to increased fuel consumption. Remove items you don’t need to improve efficiency.

Minimize idling time. Allowing your Blazer to idle for extended periods wastes fuel. If you’re stopped for more than a minute, turn off the engine. Modern engine technology allows for quick restarting without causing excessive wear and tear.

Use the Blazer’s drive modes. Experiment with the different drive modes offered (if equipped). Many models offer an “Eco” mode that adjusts engine and transmission settings to prioritize fuel efficiency. Choosing this mode, especially in city driving, can provide small improvements in gas mileage.
